Advances in Green Nanotechnology for Sustainable Pharmaceutical Formulations

Green nanotechnology is an emerging field that combines the principles of sustainability with the advanced potential of nanoscience. In pharmaceutical sciences, this approach offers safer, eco-friendly, and more efficient solutions for drug development and delivery. Instead of relying on toxic chemicals, green nanotechnology uses natural sources like plant extracts, biopolymers, and microorganisms to synthesize nanoparticles. These green nanomaterials are biodegradable, biocompatible, and often enhance the effectiveness of drugs by improving their solubility, stability, and targeted delivery. This review highlights the latest advancements in green synthesis methods, explores various sustainable nanocarriers, and discusses their environmental and therapeutic benefits. It also examines the current challenges, regulatory aspects, and future directions that can make pharmaceutical formulations not only more effective but also environmentally responsible.
